: Headlight resealing

For the ones that have resealed their headlight housings.....what did you use to seal them?

I did both housings early last year and one of them is leaking again, full of condensation inside. I used a marine grade silicon that was supposed to stay somewhat pliable, apparently it must have shrunk in this Florida sun and started leaking again. Anyway, I am planning on doing it again and was curious what you guys use? and if you have seen good results?

Thanks.

I used a Permatex Silicone Windshield sealer, like any other clear silicone but "runny", and haven't had any issues after 3-4yrs.

What parts of the housing did you seal?! Looking to seal mine and needed some insight.

Not really that hard. Any place 2 different plastics meet seal it...

I did both of mine 2 years ago with just quality clear silicone. I dont see any need to use 3M 5200 (marine stuff) or anything like that.

The key is to seal everywhere. Seal anywhere there is a chance water could get in. On my lights I put a small bead in the crack on the dust covers. And then I sealed where the front headlight lens meets the headlight housing.

If you look at the headlight you can see around the edges there is a rubber seal that is supposed to seal the lens to the housing. On my headlights the seal had shrunk and therefore was letting water in.

That's this is exactly where I was looking to seal but I was debating if I wanted to separate the lens from the housing (if possible) and seal around the rubber and put it back together or just do like you are suggesting and apply a bead of silicone around the cracks where the lens and housing meet.

I forget but a while ago I looked up separating the lens from the housing. If I remember correctly you would have to hear the whole assy up in order to seperate them.

I wouldn't.

I'll be taking this job on tomorrow after I get some silicone to seal it with. Will post how it goes.

Make sure you get all of the moisture out of the headlight before you seal it. You don't want any moisture trapped in there.

You can use a hair dryer or a heat gun (very carefully) to help speed the drying process up.
